The legal landscape of recreational cannabis production and consumption is rapidly expanding, driving a need to inform empirically supported cannabis regulatory policy. A behavioral economic framework integrating economic constructs (e.g., price, substitutability) with psychology and decision-making sciences, has previously been applied to tobacco regulatory sciences through the use of experimental marketplaces. However, experimental marketplaces have not yet been applied to understand cannabis choice behaviors or study ways to minimize risks from use. Herein, we describe the development and initial feasibility testing of an Experimental Cannabis Marketplace (ECM). The ECM can serve as an experimental platform relevant to evaluating the impact of regulatory policies on cannabis choices and use behavior. The ECM was designed to resemble an online cannabis dispensary. Adults aged 21 and older with past month cannabis use and past month purchase from a recreational dispensary were recruited online. To test the feasibility and acceptability of the ECM, 62 people completed the ECM shopping task and provided feedback on the ECM prototype. Participants also reported about their typical purchases from real-world dispensaries. Nearly all participants rated the ECM as very (80.65%) or somewhat (16.13%) easy to navigate, and rated task instructions as at least mostly clear (100%). The majority (75.81%) said cannabis products available in the ECM were mostly the same or exactly the same as at their typical dispensary. Participant purchase choices in actual dispensary purchases closely matched ECM purchases, with 88% of product choices in typical real-world cannabis dispensaries matching the ECM products purchased. Initial testing of the ECM indicates it is an acceptable and feasible tool for understanding cannabis purchasing and choice behavior. These preliminary findings suggest that the ECM mimics cannabis dispensary settings with people making similar choices to those made in the real world.
娱乐用大麻生产和消费的法律环境正在迅速扩大，这就需要用经验支持的大麻监管政策来提供信息。一个将经济学结构（例如价格、可替代性）与心理学和决策科学相结合的行为经济学框架，已经通过使用实验性市场应用于烟草监管科学。然而，实验性市场尚未被应用于了解大麻的选择行为或研究如何最大限度地降低使用风险。在此，我们描述了实验性大麻市场（ECM）的开发和初步可行性测试。ECM 可以作为一个与评估监管政策对大麻选择和使用行为的影响相关的实验平台。ECM 的设计类似于在线大麻药房。招募了过去一个月内有大麻使用和过去一个月内从娱乐性药房购买的 21 岁及以上的成年人参与在线调查。为了测试 ECM 的可行性和可接受性，62 人完成了 ECM 购物任务，并对 ECM 原型提供了反馈。参与者还报告了他们在真实世界药房的典型购买情况。几乎所有参与者都将 ECM 评为非常（80.65%）或有点（16.13%）易于导航，并表示任务说明至少大部分清楚（100%）。大多数参与者（75.81%）表示 ECM 中提供的大麻产品与他们在典型药房中的产品基本相同或完全相同。参与者在实际药房购买中的选择与 ECM 购买非常匹配，88%的典型真实世界大麻药房产品选择与 ECM 购买的产品匹配。对 ECM 的初步测试表明，它是一种可以接受和可行的工具，用于了解大麻购买和选择行为。这些初步发现表明，ECM 模拟了大麻药房的环境，人们在其中做出了与现实世界中类似的选择。
